For collaborative work flow
My flow:
> git checkout  master
>git  fetch
>git merge origin/master
now create another branch  test_website, better directly working o9n master branch
>git checkout b  test_website
//modify index.php and put in staging
>git add index.php
//then put in git repository
>git commit -m "add contact in index.php"
>git fetch
>git push -u origin test_website


My collaborator flow
> git checkout  master
>git  fetch
 >git merge origin/master
check out my work
>git checkout -b  test_website  origin/test_website
check out what I did
> git log
He make some change on the code and commit
>git commit -am "add jiansen in contact.php"
make sure the local code up-to-date using fetch 
>git fetch
push the code in remote
>git push

Back to my flow
>git fetch 
>git log -p test_website..origin/test_website
sync my local test_website
>git merge origin/test_website
go back master branch
>git checkout master 
>git  fetch
 >git merge origin/master
merge in branch test_website in master
>git merge test_website
